Definitions

  • the invention relates to a lifting device, in particular a muffle.
  • lifting devices comprising in particular a pulley making it possible to haul a load.
  • a lifting device has already been known for a very long time, in particular a muffle consisting of a yoke provided at its upper part with a hooking member, an axis and a sheave, movable on this axis and placed between the two wings of the yoke.
  • a lifting device comprising a yoke provided at its upper part with a hooking member, an axis and a sheave movable on this axis and placed between the wings of the yoke.
  • This yoke consists of two discs which, during operation, are made integral. One of the discs in this yoke has a notch for the passage of the rope.
  • the mittens, fulfilling the conditions for the two functions mentioned above, are equipped with braking baffles around which the rope is partially wound.
  • These braking baffles are located in the vertical extension of the return pulley and on the same vertical plane as the axis of symmetry of the pulley sheave. Therefore, a first disadvantage is obtained consisting in the significant elongation of the body of the muffle. However, it is very desirable that the muffle has the smallest possible height.
  • these devices include a pivoting cover for access to the baffles. This cover must be immobilized in the open position. On the other hand, it must in no case open or close without the manual intervention of the operator.
  • the rope must be threaded by hand into the baffles, which presents certain difficulties in cold, humid weather and, in the event of panic, in the event of an accident.
  • the untimely opening of the baffle protection cover can cause the rope to be ejected from the baffle housing. As a result, there is a risk of a serious accident.
  • the present invention aims to provide a solution to this difficulty.
  • the invention as characterized in the claims provides a lifting device fulfilling the conditions of a double function. Indeed, this device is used, on the one hand, in the use of a pulley with a return pulley, to mount the material fixed at one end of the lifting rope towards the anchor point of the muffle, while operating the efforts of traction from the ground and, on the other hand, hooking a load to a strand of the rope, for example an injured or inanimate agent and lowering it flexibly while exerting only a very small braking force on the other strand.
  • the invention of the device essentially lies in the design of the rope braking system.
  • the advantages obtained thanks to this invention consist essentially in that the system makes it possible to instantly transform the return pulley into a descender and thus to a single man, at the top of a support, to ensure the instant rescue of an accident victim. .
  • This braking control can take place at any level between the ground and the muffle mooring point. It is the same with regard to the blocking of the rope which becomes a self-blocking achieved by the jamming of the rope.
  • the invention relates to a lifting device, in particular, a muffle consisting of a yoke provided at its upper part with a fastening member and formed of two parallel wings, one of which has a notch, a axis and a sheave, movable on this axis and placed between the two wings of the yoke characterized in that it comprises at least one fixed sheave threaded on one end of the axis projecting with respect to the wing of the clevis in which the notch is produced and on which one of the strands of the cord wound around the mobile sheave is capable of being wound after passing through the notch produced in the wing of the clevis interposed between mobile sheave and the fixed sheave (s).
  • Figure 1 is an elevational view of the lifting device according to the invention
  • Figure 2 is a side view of this device
  • Figure 3 is an elevational view of the device in use phase descender
  • Figure 4 is an elevational view of the blocked rope device
  • Figure 5 is a side view of the device showing the cooperation of the mobile sheave and fixed sheave.
  • the device 1 includes a yoke 2 consisting of two vertical wings 3 and 4 interconnected by a transverse wall 5.
  • This transverse wall 5 is provided on its outer face 6 with a hooking member 7 such as a hook.
  • the two vertical wings 3 and 4 are crossed right through by an axis of rotation 8.
  • On this axis of rotation 8 can freely pivot a mobile sheave 9 placed between the internal faces 10, 11 of the two vertical wings 3, 4.
  • This mobile sheave 9 has a groove 12 around which a handling rope 13 is partially wound.
  • the axis of rotation 8 projects relative to one of the wings 4 and at least one second sheave 14 fixed in rotation is threaded onto this projecting end.
  • a notch 15 is made in the wing 4 allowing the handling rope 13 to pass.
  • the fixed sheave 14 has an internal flank in the form of a truncated cone 16 whose large base 17 is directed towards the external periphery 18 and the small base 19 is secured to a hub 20.
  • This fixed sheave 14 is capped by a cover made of elastomer 21 of circular shape and having a flange 22 directed towards the vertical wing 4 of the yoke 2. This flange 22 maintains the cord 13 on the fixed sheave 14.
  • the handling rope 13 is partially wound around the mobile sheave 9.
  • one of the strands 23 of the rope 13 is passed through the notch 15 and the rope 13 is wound on the fixed sheave 14. If one wishes to block the rope 13, it is sufficient to wind it several times around the fixed sheave 14. Because of the taper of the internal flank 16, the different bands 24 , 25 of the rope 13 tend to approach the hub 20 but, due to the volume of the rope 13, a self-locking is obtained by wedging the rope 13 on the fixed sheave 14. The rope is held on the fixed sheave 14 by the rim 22 of the elastomer cover 21.
